Ok, then the bug is in handling of polling mode in this particular chip.After such switch to polling mode, applications will get stuck onreleasing the soundcard. Another symptom I forgot to describe is thatthe last ~100ms of output will keep repeating when I pause/stopplayback, one has to mute the volume to get rid of this. Again, thisstarts happenning only sometimes after the switch to polling mode,but then keeps happenning fairly consistently.
